Don’t Let Wood Rot Lead to More Damage!
Wood rot can be a major problem in your crawl space and lead to structural issues. It’s typically caused by water damage and can wreak havoc on your crawl space. MidAmerica Basement Systems offers crawl space solutions to fix and control wood rot.
Typically, the supports holding up the home in the crawl space are made of wood. An open crawl space allows moisture and humidity to be able to enter into the space. Moisture and humidity do not mix with wood. With wood being in this environment it will mold and rot. Rotting wood can lead to more issues not only in the crawl space but in the rest of the home.
Approximately 20 billion board feet of timber is destroyed by wood rot in the United States each year—far more destroyed wood than is damaged annually by fire!
Replacement wood used to repair damage caused by wood rot accounts for almost 10 percent of the annual wood production in the U.S. alone.
In the United Kingdom, dry rot problems have been credited for dealing about 150 million pounds worth of damage annually, and wood rot in general leads to about 17 billion dollars of damage each year in the United States.
MidAmerica Basement Systems has a long history of experience in eliminating, preventing, and controlling dry rot infestations in homes throughout Illinois and Iowa, including Bettendorf, Pekin, Marion, Freeport, Waterloo, Muscatine, Galesburg and areas nearby.

Protect Your Home From Dry Rot!
The Bad News
- While dry rot is not the most common type of rot, it can deal serious damage to your home and endure conditions that are too dry for other types of rot to thrive. In fact, up to a 75% loss in the toughness of the wood is possible with just a 1% decrease in the wood's weight of the wood.
- Dry rot fungus spores are present in most homes and can survive for several years, waiting for the right conditions to grow.
- Dry rot can pull moisture from moist areas to dry areas. It grows through mortar, concrete, masonry, and behind plaster.
The Good News
- Despite its name, dry rot needs moisture to produce spores-- at least 28-30% moisture content within the wood with a relative humidity of 95% or higher. Most softwood timbers in dry homes, especially in the upper levels, have a moisture content of 12-15%.
- Dry rot problems in basements and crawl spaces can easily be solved by controlling moisture by sealing and dehumidifying the space.
- Treatment of the wood products such as boric acid is known to eliminate and prevent dry root fungi.
What is Dry Rot & Brown Rot?
Dry Rot is a term most often used to describe a particular kind of dry, cracking, rotting wood. However, dry rot occurs because of a variety of brown rot species, most notably the true dry rot fungus known as Serpula Lacrymans. Dry rot originally got its name from the thought that it didn't need water to live, but instead used a fermentation process to survive. Research long ago proved that theory untrue, and dry rot is now more appropriately called brown rot.
Dry rot needs much less moisture than other types of wood-rotting fungi—a wood moisture content of just 28-30%—to survive. While there is no official proof on the subject, many contractors have observed that dry rot also will not grow on wood with too much moisture.
Dry rot (also known as brown rot) is one of the most damaging forces on household wood in the world.
Identifying & Treating Dry Rot or Brown Rot Problems in Illinois and Iowa
A common first indication of dry rot in a home is the appearance of a red brick dust. This is actually an accumulation of fungal spores that are covering the surface, waiting for the proper conditions to start to grow.
An outbreak of dry rot commonly occurs several months after a household water event, such as flooding, bursting washing machine hoses, a failed water heater, or leaking pipes.
Dry rot is also common in vented crawl spaces and basements with groundwater flooding.
Dry rot is often not detected until the damage is already very significant. At this point, the following steps are recommended:
Damage from dry rot creates small, rectangular pieces of crumbling wood on the surface. Dry rot damage is often mistaken as a termite infestation.
All wood that shows decay or visible fungus should be removed, as well as all wood within one meter of the visible decayed material.
Plaster, paneling, linings, and ceilings around the dry rot areas can also contribute to the damage and should also be removed.
Using a wire brush, loose material is removed from all surfaces within 1.5 meters of the furthest edge of the infestation, including metal, masonry, and pipes. Resulting dust and debris is removed as well.
A disinfectant is applied to all wood, masonry, and exposed soil in within 1.5 meters from the damage.
Substantially rot-damaged beams, joists, and posts are replaced with pressure-treated wood.
Remove all standing water sources, then install a plastic vapor barrier on the walls and floors. Install a self-draining dehumidifier powerful enough to dry the area. (At least a 100-liter model)
Seal off all crawl space vents and door covers. Encapsulate the crawl space with a crawl space liner, then install a self-draining crawl space dehumidifier.
Dry Rot Alert!
Architect's Journal reports that dry rot can grow through damp mortar, concrete, masonry and behind plaster.
This makes remediation of dry rot complicated and expensive, and it can lead to future problems with dry rot if it is not treated properly.
